在数据库插入函数中使用 $_GET 变量？

Question

希望有人能对我遇到的问题有所了解。

我有一个用于向页面添加评论的表单；

    <?php if(app('current_user')->role != 'user'): ?>
        <div class="leave-comment">
            <div class="control-group form-group">
                <h5><?= trans('leave_comment'); ?></h5>
                <div class="controls">
                    <textarea class="form-control" id="comment-text"></textarea>
                </div>
            </div>
            <div class="control-group form-group">
                 <div class="controls">
                    <button class="btn btn-success" id="comment">
                        <i class="fa fa-comment"></i>
                        <?= trans('comment'); ?>
                    </button>
                </div>
            </div>
        </div>
    <?php else: ?>
        <p><?= trans('you_cant_post'); ?></p>
    <?php endif; ?>

这里使用ajax来加载下面的case；

case "postComment":
    echo app('comment')->insertComment(ASSession::get("user_id"), $_POST['comment']);
    break;

哪些加载；

public function insertComment($userId, $comment)
{
    $userInfo = $this->users->getInfo($userId);
    $datetime = date("Y-m-d H:i:s");

    $this->db->insert("as_comments", array(
        "posted_by" => $userId,
        "posted_by_name" => $userInfo['username'],
        "comment" => strip_tags($comment),
        "post_time" => $datetime,
        "FK_DappID" => 1
    ));

    return json_encode(array(
        "user" => $userInfo['username'],
        "comment" => stripslashes(strip_tags($comment)),
        "postTime" => $datetime
    ));
}

cmets 在一个名为 view.php 的页面上使用，我有一个变量，它是从名为 $_GET['ID'] 的 htis 页面的 URL 设置的。

所以..

如何将要插入数据库的数组中的 "FK_DappID" => 1 更改为 $_GET['ID'] 的值？

我尝试过使用 "FK_DappID" => $_GET['ID'] 但它不起作用..

任何帮助都会非常感激。

谢谢，B.

//comment button click
$("#comment").click(function () {
    //remove all error messages
    asengine.removeErrorMessages();

    var comment = $("#comment-text"),
         btn    = $(this);

    //validate comment
    if($.trim(comment.val()) == "") {
        asengine.displayErrorMessage(comment, $_lang.field_required);
        return;
    }

    //set button to posting state
    asengine.loadingButton(btn, $_lang.posting);

     $.ajax({
        url: "ASEngine/ASAjax.php",
        type: "POST",
        data: {
            action : "postComment",
            comment: comment.val()
        },
        success: function (result) {
            //return button to normal state
            asengine.removeLoadingButton(btn);
            try {
               //try to parse result to JSON
               var res = JSON.parse(result);

               //generate comment html and display it
               var html  = "<blockquote>";
                    html += "<p>"+res.comment+"</p>";
                    html += "<small>"+res.user+" <em> "+ $_lang.at +res.postTime+"</em></small>";
                    html += "</blockquote>";
                if( $(".comments-comments blockquote").length >= 7 )
                    $(".comments-comments blockquote").last().remove();
                $(".comments-comments").prepend($(html));
                comment.val("");
            }
            catch(e){
               //parsing error, display error message
               asengine.displayErrorMessage(comment, $_lang.error_writing_to_db);
            }
        }
    });
});

});

您正在使用type: "POST" 提交您的ajax，因此数据将在您的PHP 中的$_POST 变量中可用。

因为看起来您正在添加评论，所以这是要使用的正确请求动词，因此请在您的插入方法中更改为 "FK_DappID" =>$_POST['ID']，并确保将 ID 添加到您在 AJAX 中发布的 data ：

您应该创建一个隐藏的表单输入 <input type="hidden" id="post_id" name="post_id" value="<?= $_GET['ID'] ?>" />，然后从该输入中获取值以发送到您的 AJAX POST 请求中。

data: {
  action : "postComment",
  comment: comment.val(),
  ID: $("#post_id").val()
}
